This is just one of hose spontaneous thoughts but has anyone successfully fitted a Supercharger to run along side as Turbo engine?
In reality the Supercharger spins up a lot quicker than the turbo with it being belt driven etc, so this could take up any lag from the turbo whilst it is spinning up to acheive max boost!
Now in theory you would fit the Supercharger between the Turbo & Air filter and this would obviously spin and draw in the air before the turbo reaches its boost, thus providing you with an initial boost where you would normally experience lag, as i said before! and the benefit of this extra charge of air brought about by the supercharger would also cause the turbo to spin up quicker.
The next benefit of this, is that as we all know Superchargers dont provide the power for as long a period as a Turbo, so as the supercharger die's out so to speak the turbo would be at its maximum boost (or there abouts).
Finally in my small knowledge of Superchargers, I understand that they are more or less totally mechanically operated, so there's no need for a special ECU etc to run them which would simplify this quite a lot and also you would proabably need to fit a dumpvalve between the Turbo & Supercharger to stop it from stalling due to the air trapped between the Turbo & itself??
Therefore in vague terms, from the moment you accelerate you will have the initial power response that you require (and a hell of a lot more), untill the turbo reaches its max boost...Wehay!!
Sorry if this has bored anyone but like i say it was just one of those thought's!!
